Hi,
What do i need to improve my 60' ? I don't know much about suspension and I'm hoping that you guys can point me to the right direction. I'm not expert but i think something is wrong with the way my car launches.
my setup is:
6 point roll bar
eibach drag springs cut 1 inch
70/30 front 50/50 rear.
rear upper and lower control arms (i don't remember the brand but i think they are lakewoods) i bought them 7 years ago. they are red if that helps
tire pressure 11.5 rear, 35 front.
i launch with about 5-6 psi of boost and the 2 step is set at 3200.

on this pass i did a 1.47 60'

I am certainly not an expert at drag suspension but judging by the picture a good anti roll bar in the rear would help big time.

 

I can't see pis,cuz I'm on my phone. If its the twisting commonly seen in stangs? Many run an airbag on one side or an anti-roll bar is needed if stiffining the chassis won't help. 1.47 60ft is not bad though

 

x2 on the anti roll bar. Also some more cage to stiffen the chassis. OH and also sub frame connectors.

 

i have welded sub frame connectors.
what freaked me out the most in the pic is the rear driver side tire, it seems pushed too far outside the fender.

 

Holly crap that sucker is twistin!
Anti roll bar!

 

My old car did the same thing when I first started racing it. An anti-roll bar will fix that.

 

nother vote for a ARB to start

 

Thanks guys, i really appreciate it.
I just ordered a competition engineering anti roll bar. it should be here next week.

 

Cancel your order if you can. I have heard people having trouble with the ends not staying tight on the bar. Team Z is the real deal get a bar from them and you will never have to worry about it.

 

cancel it..those suck..the center tube is hoolow, and the bolt twist thru it

 

CANCEL THAT.....big mistake u made by ordering comp eng., order team Z ......the GOD of SUSPENION

 

Cancelled

I'll call Team Z on monday, I sure hope they have it in stock. I need it for a race in 2 weeks.

 

yes we have them in stock!

 

this was great advice. I started out with the C.E. (I have a big boy ARB now) my car at launch didn't look much better than the car in question here.

 

I'm about to order the ARB from TeamZ. But should i remove the air bag in the right spring?

 

Yes, remove it.

 

You also need to check your torque boxes, with the way that the rear end is moving from side to side I wonder if there is something under there that is flexing to much. Weld them up at least or if they are shot then order some new reinforcements. They made a noticable difference in my car big time!
